SPECIFICATION forming part of Letters Patent No. 752,032, dated February16, 1904.

I Application filed June 17, 1903. Serial No. 161,870. (No model.)

To all whom it may concern:

Be it known that I, CHRISTEN N. CHRISTEN- SEN, a citizen of the UnitedStates, residing at Meriden, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inUmbrellas, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to new anduseful improvements in umbrellas, and hasfor its object, among other things, the construction of an umbrella withparts so connected that the umbrella may be folded whereby it willoccupy the minimum amount of space.

To these and other ends my invention consists in the umbrella havingcertain details of construction and combination of parts, as will behereinafter described, and more particularly pointed out in the claim.

Referring to the drawings, in which like numerals of reference designatelike parts in the several figures, Figure l is a view of the umbrellashown in its closed position. Fig; 2is an enlarged fragmentary view ofan umbrella with my improvements shown in its open position; and Fig. 3is a fragmentary detailed view of one of the ribs, extension-ribs, andstretchers. i

In carrying out my invention I construct the umbrella-rod preferably ofthree sections, (designated in the drawings, 1, 2, and 3,) whichsections are slidable within each other telescopically and are held intheir open positions by the springs 4, which are of the ordinaryconstruction and project through a slot in the side of said sectionswhen in register therewith, as shown in Fig. 2. Any means can be used tohold these sections in their extended positions, and I do not,therefore, limit myself to the use of a spring such as the one shown anddescribed herein.

Adjacent to one end of the section 1 is the head 5, to which the ribs 6are fixed thereto in any preferred manner. These ribs are preferablytubular in form, having a longitudinal slot 7 in the under side thereof,which extends substantially the whole length of said ribs, and in theupper side near the outer end thereof is a slot 8. Slidable within saidribs 6 are the extension-ribs 9, having a radially-projecting lug 10adjacent to the inner end thereof and to which is secured one end of thestretchers 11, the other end of which is secured to the umbrella-runner12, slidable upon the rod in the usualmanner. The extension-ribs 9 whenthe umbrella is closed are within the interior of the ribs 6, and theouter ends of said extension-ribs are substantially flush with the outerends of said ribs. hen the umbrella is opened, the extension-ribs aredrawn outwardly until the stretchers 11 engage the outer end of the slot7 when the inner ends of the extension-ribs 9 are canted, so that thelug 1O thereon enters the slot 8 in'the rib and is thus held in itsoutward position.

The numeral 13 designates the umbrellacover, which is preferably made oflightweight rubber and is secured at its outer edges to the outer endsof the extension-ribs 9 in any preferred manner, the specific means fordoing which not being material to my invention is not shown or describedin detail.

To open the umbrella, the section 3 is first grasped and drawn outwardlyand until the spring t therein registers with the slot in the section 2and is there held against further movement. The section 2 is then drawnoutwardly until the springt therein engages the recess in section 1. Therunner 12 is now grasped between the fingers and slid over the sections1 and 2, the spring 4 in the section 2 being depressed sufiiciently atthis time to permit it to pass. This movement of the runner draws theextension-ribs 9 outwardly through the ribs 6 until the stretchers 11engage the end of the slot 7. During this operation the rubber covering13 is stretched with the movement of the extension-ribs 9. The positionof the runner is then reversed, it being moved on the sections towardthe'head 5, and immediately the position of the runner is reversed thestretchers 11 are moved lengthwise slightly and the lugs 10 upon theextensionribs 9 are thrown into the recess Sin the ribs 6, thuspreventing a return movement of the extension bars 9. \Vhen the runnerhas passed the spring at in the section 2, it is released and heldagainst a downward movemen t by its engagement with said spring.

To close the umbrella, the spring 4, just referred to, is pressedinwardly a suflicientdistance to permit the runner to pass the same, andthe runner is moved on the rod until'the ribs are brought paralleltherewith. The outer ends of the extension-ribs 9 are then grasped inthe hand and canted sufficiently to release the lugs 10 from the slots8, after which the runner 12 is moved along the rod toward the head 5,sliding the extension-ribs 9 into the ribs 6 and bringing the ribs 6,extension-ribs 9, and stretchers ll parallel with and against thesection 1. The closing of the umbrella is facilitated by the contractionof the rubber cover 13, which is released as soon as the lugs 10 aredisengaged from the slots 8.

The cover 13 is preferably secured to the rod by a nut 14:, which isthreaded upon the end of section 1, this manner of securing the coverpermitting the same to be readily remouled and another one attachedthereto, if desire There are many minor changes and alterations that canbe made within my invention aside from those herein shown and suggested,

amass claim as new, and desire to secure by Letters umbrella-rodconsisting of telescoping sections; of a head secured to said rod;tubular ribspivotally secured to said, head and having a slot in theunder side thereof and another slot in the top thereof shorter than thefirstmentioned slot and near the outer ends of said ribs; extension-ribsmovable within said tubular ribs and having rigid lugs upon the top sideand near the inner ends thereof; a runner upon said rod; stretcherspivotally secured to said umbrella runner at one end, passing throughsaid under slot and pivotally secured to the aforesaid extension-ribs atthe other end, said stretchers being so arranged that the engagementthereof with the outer end of said under slots will cant saidextension-rods so that said lugs will be thrown into said top slots andthere hold said extension-ribs against withdrawal while said stretchersare held in their open position; and a rubber cover connected with saidrod and ribs.

In testimony whereof I aflix my signature in presence of two witnesses.
